Patio: are you talking about Windows Defender? Windows Defender has been described as less than Avast or Bit Defender. The reason I changed antivirus programs was because of that. I surf pretty cleanly but there is always a chance for me to mess up. I may eventually go back to Windows Defender and MBAM, time will tell.
Allen: I didn't know whether a problem existed or not because Windows Defender is pretty much silent and MVAM trial period isn't always available.
